Every shop that handles payments in btc can easely add UTRUST, I mean why not? If you already accept payments in crypto, meaning you're somehow a crypto enthusiast, better integrate it with a platform offering buyer protection
The platform has to prove it's usefulness, reliability, security etc before any biz will feel comfortable routing their customer's payment info thru the platform. Earning such trust in the crypto space is not an easy feat. That's why i say it will take yrs of proving it's viability before we can start discussing partnerships.
